Sealing Bw Article

Putty type sealing BW article:
BW water line to be the import of special rubber, inorganic absorbent materials, such as high viscosity resin material by more than ten kinds of mixing, kneading, squeezing to form, which is the basis of foreign products successfully developed by a cross-section of four square self-adhesive strips intumescent water sealing article. Rely on their own pre-paste viscosity directly in the concrete construction joints, after the pouring of the interface crack, the second after pouring concrete (was wrapped in a state of concrete). The product will be gradually inflated with water, on the one hand to plug the gap that may exist in the pores, on the other hand, exposure to concrete interface more closely, resulting in a larger anti-water pressure, the plasticity of the formation of impermeable colloid, with the expansion of the product high magnification, mobile complementary, and at construction joints, joints after pouring a strong balance after the self-healing function, self-sealing due to the new settlement of small cracks have been completed for the project, such as water leakage gap can be re-plugging of the water, the use of the water be low-cost construction technology and simple, the best corrosion resistance.
Characteristics:
1, expansion of water, "water seal";
2, slow expansion, water ≤ 186h largest expansion of its expansion rate of 50%;
3, construction convenient, low cost
4, non-toxic non-polluting
5, in the long under water without Dissolved precipitates;
6, with other hydrophilicexpansion are compared to the largest expansion of its water by the expansion of long-term after repeatedly not lost.
Proposed construction technology
reserved for paste-like manner, before pouring concrete in the water need to be placed on the reserved slot (available on the template set aside wooden nail).
Removal of the first poured concrete template, clear the surface, so that surface water joints, clean, no debris.
Will be embedded water reserve tank. If we do not reserve slots on the vertical crack length can be added to the binder paste, or use concrete nails with wooden bar to fix sealing; on the level of joints can be directly pasted on the concrete surface.
(4) Article sealing paste as soon as possible after the concrete pouring.
(5) paste in the installation process, should be the prevention of water pollution and the role of water in order to avoid the use of sound effects of King.
